The inverter is the heart of the photovoltaic system. All the electricity generated by the solar panel must be processed by the inverter before it can be output to the outside. The high-performance solar inverter plays an important role in the operation of the entire system. The following is for you Introduce the inverter.
Inverters, also known as power regulators and power regulators, are an essential part of photovoltaic systems. Usually, the process of converting DC power into AC power is called inverter physically, and the device that realizes the inverter process is called inverter equipment or inverter. Hence the name of the inverter. The main function of the photovoltaic inverter is to convert the direct current generated by the solar panels into the alternating current used by household appliances.
The maximum power tracking function ensures the maximum output power. The current and voltage of the solar panel change with the intensity of solar radiation and the temperature of the solar cell module itself, so the output power will also change. In order to ensure the maximum output power, we must try our best It is possible to obtain the maximum output power of the solar panel. The MPPT tracking function of the inverter is designed for this characteristic. MPPT tracking is also called maximum power point tracking. According to calculations, the power generation of the system configured with MPPT tracking can be 50% higher than that of the system without MPPT tracking. Therefore, if you want the photovoltaic system to generate more electricity, don’t just look at the solar panels. How much of the electricity generated by the solar panels can be effectively output in the end depends on the inverter.
Anti-separate operation function to ensure the safety of the power grid
When installing a photovoltaic system, many people hold the mentality of "even if the power grid fails, their home can still use electricity". Little do they know that when the power grid fails, their photovoltaic system will also stop operating.
The reason for this phenomenon is that the inverter is equipped with an anti-islanding device. When the grid voltage is 0, the inverter will stop working. Hearing this, do you feel trapped? Don’t worry, please continue to look down. The anti-islanding device is a must-have device for all grid-connected photovoltaic inverters. The reason for this is mainly for the safety of the power grid. Imagine that the power grid is out of power, and the grid staff has already gone into battle. Check and repair the circuit, while your home's photovoltaic system is still continuously uploading electricity, it is easy to cause safety accidents.
If you really want to use electricity in your own home when the grid is out of power, you can consider installing a photovoltaic off-grid system, so that the electricity generated by solar panels will be stored and used when users need it .
According to the output power of the solar panel, automatic operation and shutdown After sunrise in the morning, the solar radiation intensity gradually increases, and the output of the solar battery also increases accordingly. When the output power required by the inverter is reached, the inverter will start Start running automatically. After starting to run, the inverter will monitor the output of the solar cell components all the time. As long as the output power of the solar cell components is greater than the output power required by the inverter, the inverter will continue to run; it will stop until sunset, even on cloudy and rainy days. The inverter also works. When the output of the solar cell module becomes smaller and the output of the inverter is close to 0, the inverter will form a standby state.
The above are just some basic performances of the inverter. High-performance solar energy is an important and complex part of the photovoltaic system. A reliable photovoltaic system requires a reliable photovoltaic inverter.
